To all whom it may concern: Y

Be it known that I, JOHN W. PAGE, a citizen of the United States, residing at Quitman, in the county of Cleburne and State of Arkansas, have invented certain new and useful Improvements in Railway Signaling Devices, of which the following is a specification, reference being had to the accompanying drawings. 1 a

This invention comprehends certain new and useful improvements in railway signal ing devices, and the invention has for its primary object a simple and eflicient construction of mechanism of this character, wherebythe engineer of a train may at all times keep the road clear ahead of him and apprise others in advance by displaying danger signals that his train is approaching a certain station or block.

The invention also has for its object a simple and efiicient construction of mechanism of this character which will be practically automatic in all of its workings, which will be easy to maintain and not liable to get out of order, and which will include trip levers arranged at predetermined intervals alon the track, whereby when a train approac es a certain point, say one station on the road, a device carried by the engine will engage one of said trip levers andimmediately a danger signal at the next station will be brought. into view, while subsequently, after the train has reached such signal, the trip lever at the signal station Wlll be also engaged by the device carried by the locomotive and the signal automatically returned to its clear track position. Andthe invention also aims to generally improve this class of devices and to render them more useful and commercially desirable.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full-understanding of the invention, reference is to be had to the following description and accompanying drawings in which,

View in the nature of a diagram; and Fig. 5 is a horizontal section of the device illustrated in Figs. 1 and 3.

Each of-my improved signaling devices for railway work, includes a battery box 1. intended to be located alongside of the track at a station or other predetermined point, said box, in the present embodiment of the invention, being provided on its interior with a ledge or platform 2, upon which a relatively stationary contact plate 3 is mounted. A contact key 4 is held by a supporting arm 5 in juxtaposition to and normally slightly spaced from the contact plate 3, said supporting arm 5 being secured at one end to one wall of the box 1 and being held in its normal elevated and inoperative position by a spring 6. An actuating rod 7 is secured at its lower end to the supporting arm 5 and extends upwardly through an opening 8 formed in the top of the box, the upper end of the rod 7 protruding, as clearly illustrated in the drawings, and being designed for engagement by a cam 9 formed on a trip lever 10 which is tulcrumed in be tween standards 11 supported on the top of the box and which is held normally in an upright position by means of a spring 12.

y invention also includes a motor box'l3 which is also disposed along the tra k and located at any predetermined point, say at the next station from the station or point where the battery box 1 is located. An electric motor 14 is supported within the box 13 with its shaft 15 disposed vertically. said shaft being secured at one end to a vertically disposed stafi 16 which projects up through an opening 17 formed in the top of the box 13. A transversely disposed and vertically projecting stand 18 is mounted on the top of the box 13, said stand being formed with openings 19 and 20 on opposite sides of the stafl 16, through which white and red lightsv are designed to show, the suitable for. this purpose being mounted on behind the stand. Thestand is also in one face with a cavity or recess 21 designed topartially or entirely house the staff. A flag 22 which is painted red on one side and white on the other and which may bein the form of a sheet metal plate or the like, is secured to the statl 16 in perpendicular relation thereto and is designed to be swung over from one side of the stand to the is rotated in one dir c- A cable 23is secured lanterns the box formed and engages it long enough for the motor 14 the stall? 16, said cable extending through an t opening 2i formed in the wall of the cavity 21 and being secured at its other end to a spring 25 which is connected to a trip lever 26 normally held in a vertical position by a spring '27. By means of the spring 25 that is secured to the cable, the connection between the trip lever 26 and staii l6 w1ll be permitted to yield so as to avoid strain upon the parts in the operation of the device.

In carrying out my invention, one lead 28 of the motor 14 is connected to one terminal 29 of the battery 30 in the box 1. The other lead 31 of said motor is connected to the key 4 and the othdr terminal 32 of the battery 30 is connected by a rod 33 with the relatively stationary contact plate 3.

From the foregoing description in connection with the accompanying drawings, the operation of my improved railway signal will be apparent.

In the practical use of the device, when a train approaches the point where the battery box 1 is located, the engineer will move into operative position some device on the locomotive, whereby such device will move in a path where it will strike the trip lever 10. This device which is carried by the locomotive is not shown, nor is it specifically described, as it may be of any desired form or construction, and is of itself no part of the present invention. As the lever 10 is tripped, it is obvious that its cam 9 will press downwardly upon theactuating rod 7 and consequently, the circuit will be closed by the engagement of the key 4 with the relatively stationary contact plate 3. Thus, the motor 14 will operate to turn the staff 16 in a direction to swing the flag 22 around so that its redside will show by day and the red light will. be exposed to view by night. Thus, the engineer of the train may keep his track clear ahead of him, and as the locomotive reaches the trip lever 26, it will operate the latter and such lever will be moved in a direction to pull upon the cable 23 so as to return the staff 16 to its initial position with the white side of the flag 22 showing by day and the white light by m 'ht, indicating that the road is clear. Pre erably, the motor box 13 is provided on its top with a spring catch 34 designed to engage the flag 22 when it is swung over by the rip erat-ion of the motor 1.4:, it being, of course, understood that this catch will readily yield so as to release the flag when the same is returned to its initial or clear track position by the actuation of the trip lever 26. Although the engagement of the device carried by the locomotive or car with the lever 10 does not continue for any great length of time, yet it rides over and upon said lever to act in the desired way, for it will be understood that such motor is of relatively terraces light voltage and sensitive to relatively light currents, as it is only required to swing the flag 22 through a short are, and hence, is not required to run a long time. lit is manifest that the motor is a light one, owing to the fact that otherwise should the current remain closed after the flag 22 has been swung around as far aspossible, there would be a tendency to injure the parts.

ilhile the accompanying drawings illustrate what I believe to be the preferred embodin'ient of my invention, it is to be understood that the invention is not liinited'thereto, but that various changes may be made in the construction, arrangement and proportions of the arts without departing from the scopeot die invention, as defined in the appended claims. It is also to be understood that there is a signal and a battery box with its correlated devices at each point or station along the road.

What I claim is 1. In a railway signal of the character described, an electric motor, a circuit there for, arranged to be closed at a remote point, a box in which said motor is mounted with its shaft disposed in a vertical position, the box being formed in its to with an opening, a vertically disposed sta mounted 111 said opening and connected at its lower end to the shaft of the motor, a stand mounted on the top of the box and formed with openings for light to shine theretlirough on opposite sides of said staff, a signal flag projecting horizontally from and secured to said Stan and designed to be swung over the close one of said openings upon the actuation of the motor, and a trip lever operatively connected to said staff and designed to move the same ,in a direction to swing the flag over the other opening.

2. In a railway signal'of the character described, an electric motor, a circuit therefor,

arranged to be closed at a remote point, a box in which said motor is mounted with its shaft disposed in a vertical position, the box being formed in its top with an opening, a vertically disposed statli' mounted in said opening and connected at its lower end to the shaft of the motor, a stand mounted on the top of the box and formed with openings for lightto shine therethrough on op posite sides of said staff, a signal flag project mg horizontally from and secured to said stait and designed. to be swung over to close one of said openings upon the actuation of the motor, a cable secured at one end to the staff, and a trip lever connected to the other end of said cable, for the purpose specified.

3. In a railway signal of the character de scribed, an electric motor, a circuit therefor arranged to be closed at a remote point, a box in which" said motor is mounted with its shaft disposed in a vertical position, the box being formed in its top with an opening, a

vertically disposed start mounted in said opening and connected at its lower end to the shaft of the motor, a stand mounted on the top of the box and formed with openings for light to shine therethrough on opposite sides of said staff, a signal flag projecting horizontally from and secured to said staff and designed to be swung over to close one of said openings upon the actuationof the motor, a cable connected at one end to said staff, a trip lever, and a spring connecting the other end of said cable to the trip lever, for the purpose specified.
